Today, I will talk to you about how to use LoadBalancerRule to achieve load balancing in Ribbon. Many people may not know much about it. In order to make you understand better, the editor summarized the following. I hope you can get something from this article.

The version of Ribbon is 2.3.0.release.

All of these complex equilibrium implementation classes implement the com.netflix.loadbalancer.IRule interface, and several implementation classes are provided in zuul:

AvailabilityFilteringRule

BestAvailableRule

RandomRule

RetryRule

RoundRobinRule

WeightedResponseTimeRule

ZoneAvoidanceRule

The AbstractLoadBalancerRule is as follows List-1:

List-1

Public abstract class AbstractLoadBalancerRule implements IRule, IClientConfigAware {private ILoadBalancer lb; public AbstractLoadBalancerRule () {} public void setLoadBalancer (ILoadBalancer lb) {this.lb = lb;} public ILoadBalancer getLoadBalancer () {return this.lb;}}

As shown in List-1 above, ILoadBalancer provides the ability to get a list of services.

List-2 IRule interface

Public interface IRule {Server choose (Object var1); void setLoadBalancer (ILoadBalancer var1); ILoadBalancer getLoadBalancer ();}

In List-2, the choose method is to select the interface of the service, and different implementation classes have different internal selection algorithms.

After reading the above, do you have any further understanding of how to use LoadBalancerRule to achieve load balancing in Ribbon? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
